3.8.7 Recommendations for pits and tanks made of non-conductive materials
If you have a device with a single rod or a single cable probe and a thread connection,
obey these instructions:
• Put a metal sheet between the device and the process connection.
i It must have a diameter greater than 200 mm / 8¨.
• Make sure that the metal sheet is in contact with the thread stop on the device.
We recommend that you use DN≥200 / ≥8¨ for flange connections.
If you have a device with a double rod, double cable or coaxial probe, you can ignore these
instructions.
